VIOS partitions with SLI-4 enabled Emulex adapters will be capable of driving I/O in parallel through mulitple work queues or channels, and with new hypervisor firmware that supports multiple interrupt sources an ibmvfc NPIV single initiator can be modified to exploit end-to-end channelization in a PowerVM environment. VIOS hosts will also be able to expose fabric perfromance impact notifications (FPIN) via a new asynchronous event to ibmvfc clients that advertise support via IBMVFC_CAN_HANDLE_FPIN in their capabilities flag during NPIV_LOGIN. This patch introduces three new Management Datagrams (MADs) for channelization support negotiation as well as the FPIN asynchronous event and FPIN status flags. Follow up work is required to plumb the ibmvfc client driver to use these new interfaces.
